Title: Recovery of protein
IPC: A23L2/66
Filed: 1975-12-31
Abstract: 1507880 Isolating protein from seeds GRAIN PROCESSING CORP 31 Dec 1975 [2 Jan 1975] 53355/75 Heading C3H Protein is obtained from a vegetable protein source by successively subjecting it to an isoelectric wash, digesting in water at pH 2 to 6 in the presence of acid phytase and separating a liquid extract containing soluble protein from the insoluble digestion residue. Adjustment of pH may be effected by addition of organic acids or inorganic acids and bases. Preferably the acid phytase is added at 30 to 70 C. so that a major part of the phytic acid present is hydrolysed. The process may be used to separate protein from soybeans, peanuts, cottonseeds, sesame seeds, sunflower seeds and rapeseeds. Optionally the protein source material may be treated with a proteolytic enzyme, e.g. a fungal protease derived from Aspergillus niger. Examples describe the isolation of protein from soybeans, cottonseed and rapeseed sources.

Title: Improvements in or relating to braking arrangements for trailer-pulling vehicles
IPC: B60T13/36
Filed: 1966-11-30
Abstract: 1,134,929. Tractor-trailer compressed air braking systems. WESTINGHOUSE BREMSENUND APPARATEBAU G.m.b.H. 30 Nov., 1966 [3 Dec., 1965], No. 53554/66. Heading F2F. In a compressed-air braking arrangement for tractor-trailer vehicles comprising a compressed air supply line 6<SP>1</SP> between the air reservoir 1<SP>1</SP> of the vehicle and a first coupling 8<SP>1</SP> for the trailer and containing a pressure control valve 5<SP>1</SP>, a brake control line 10<SP>1</SP> joining the air reservoir with a second coupling 12<SP>1</SP> for the trailer, and a pressure blocking relay valve 9<SP>1</SP> connected to the brake control line 10<SP>1</SP> and further connected to a point in the air supply line located between the pressure control valve 5<SP>1</SP> and the first coupling 8<SP>1</SP>, a shut-off device 22 is connected immediately after the pressure control valve 5<SP>1</SP> in the supply line and before the point of connection of the relay valve 91 with that line, the arrangement being such that the trailer braking system is connected between the first and second coupling 8<SP>1</SP>, 12<SP>1</SP> respectively so that braking of the trailer is maintained regardless of the condition of the shut-off device or couplings. Should the trailer be uncoupled when standing on a slope after the handbrake valve 4<SP>1</SP> has been operated, the shut-off device 22 must be closed and the couplings 8<SP>1</SP> and 121 must be open, the shut-off device 22 being closed first. The trailer remains braked becuase when the coupling 8<SP>1</SP> is opened the chamber 18a<SP>1</SP> of the trailer control valve 18<SP>1</SP> is vented and due to the known construction of the valve 18<SP>1</SP> automatic braking is effected. If, on the other hand, the coupling 12<SP>1</SP> is opened first, the chamber 25 in the pressure blocking relay valve 9<SP>1</SP> is immediately vented and the inlet valve 26 is opened to provide automatic braking of the trailer. The pressure control valve 5<SP>1</SP> and the shut-off device 22 may be combined to form a single structural unit as also can the first coupling 8<SP>1</SP> and the shut-off device 22.

Abstract: 1420640 Dolls MARVIN GLASS & ASSOCIATES 20 Nov 1973 [7 Feb 1973] 53779/ 73 Heading A6S A doll has at least one of its arms 14, 16, Fig. 1, raised by a motor within its body from a lowered to a raised position, Fig. 2, so that a simulated blanket 172 is raised to cover at least part of its face. As shown, first one arm 14, 16 is raised, then the other, and finally both together. As the arms 14, 16 move, the doll's head nods from side to side. A spring motor 90, Fig. 3, wound by pulling a cord extending through the doll's back, drives a shaft 104 connected through the train of gears shown to a friction drag speed governor 148. A belt 146 between pulleys 142, 144 silences the train. Cams 110, 112 (see also Figs. 4, 5) and a cam 160, fast on the driven shaft 104, are engaged respectively by spring biassed pivoted cam followers 114, 116, 162. The cam follower 114 has an arcuate end with teeth 112 meshing a gear 58 fast with the doll's arm 14, which is thus raised and lowered by rotation of the cam 110. Similarly, the cam follower 116 drives a gear 60 fast with the doll's other arm. The follower 162 turns a bellcrank lever 168, Fig. 5, which raises and lowers a link 82, pivoted on a rod 80, Fig. 3, to one side of a main pivot rod 72a connecting the doll's head to its body: thus up-and-down movement of the link 82 nods the doll's head 22 from sideto-side about the pivot rod 72a. The doll's eyes are weighted for pivoting about generally upright axes so that they seem to glance in the same direction as the head nods.
